Description
Technical field
The method that embodiment herein is generally related to test equipment and is executed by test equipment.More specifically, herein
Embodiment be related to realize communication node test.
Background technique
Active antenna system (AAS) is the pith of long term evolution (LTE) development, and is that the 5th generation (5G) is mobile logical
The major part of letter.AAS is a generic term, wireless comprising a large amount of individually transmitters and antenna element commonly used in describing
Base station, these transmitters and antenna element can be used as integrated products for multiple-input and multiple-output (MIMO) and beam forming.
MIMO realizes the multiplication of wireless link capacity by using multiple input antennas and multiple output antennas.Beam forming can be by
It is described as the signal processing technology of the directionality sent and received for controlling wireless signal.The base station AAS is defined as by 3GPP
" the BS system for being combined aerial array and active transceiver cell array and wireless distribution network " (3GPP TS 37.105
V13.0.0 (in March, 2016), version 13).According to 3GPP, AAS has the radiation mode that can dynamically adjust.In " normal " base
It stands in (that is, base station as the non-base station AAS), wireless device and antenna are separation.In addition, normal Base Station is without such as AAS
The ability of the advanced Antenna characteristic of base station etc.
As industry develops towards higher frequency and needs more complicated array antenna geometry required to realize
Link budget, AAS will become 5G one of critical aspects.At higher frequency (such as 15GHz, 28GHz or higher), propagate
Loss is much larger than the propagation loss under currently used frequency band (such as about 1-2GHz).Furthermore, it is contemplated that base station transmission will be micro-
Occur in higher frequency band in wave and millimeter wave region.Because the transmission power of both base station and user equipment by physical constraint and
Consideration (such as base station electromagnetic field (EMF) and user equipment specific absorption rate (SAR)) limitation, so only by increase
Transmission power, it is impossible to compensate increased penetration loss and (be wider than normal bandwidth, normal bandwidth is for example in broader bandwidth
About 1-20MHz) in enough Signal to Interference plus Noise Ratio (SINR) is provided.In order to realize high data rate (such as 1 gigabit/sec) institute
The link budget needed, beam forming will be required.Thus, it is expected that integrated active array builds the mainstream base station for becoming the 5G epoch
If practice.
Imagining new wireless (NR) and 5G will operate in than current higher frequency band.For example, for the first system of Japan
(first systems) is discussed 4 Gigahertzs (GHz), and 2019 world's wireless communication session (WRC19) height can be distributed
Up to the frequency spectrum of 6GHz.In future, it is contemplated that International Telecommunication Union (ITU) and/or zone supervisors mechanism can be distributed in range 10-
Microwave and millimeter wave frequency spectrum in 100GHz.
Antenna, base station, AAS etc. can be tested with ensure they meet specification or only characterize it.It can be in the test phase
Between the parameter that measures may, for example, be transmission power, the unwanted emission of radiation, antenna gain, radiation mode, beam angle, pole
Change, impedance etc..Test can be executed in different range (such as far-field range, near field range, free space range etc.).
Within the scope of far field test, test equipment (antenna (AUT) also referred to as to be measured) is placed on the remote of exploring antenna
In (exploring antenna is such antenna: it can send power to test equipment or receive power from test equipment, and
With known radiation mode and feature).In far field, the radiation mode of test equipment will not be with test equipment and detection day
The distance between line and change shape.
Within the scope of near space, test equipment and exploring antenna are close to each other.
Free space range is designed to simulation will be in space (that is, wherein inhibiting as far as possible from neighbouring object and ground
The back wave in face) in execute measurement measurement position.Anechoic room is an example of free space range measurement position.
CATR is that one kind can be used for being likely difficult to acquire test using traditional Free-space measurement method wherein and set
The tool of antenna system test is provided under the frequency of standby far field spacing.In CATR tool, carry out back wave using reflector.
Antenna reference point (ARP) is a point in somewhere in interface between radio and antenna for base station.ARP is used as
Reference in measurement and test, and various parameters can be measured relative to ARP.Access in AAS base station products, to ARP
It will be limited or will be unavailable.Therefore, on the contrary it will not be possible to execute in traditional specifications (such as TS 25.141, TS 36.141, TS
37.141 and TS 37.145-1) in include uniformity test requirement in the conduction measurement that finds.In addition, research and development (R&D) rank
All radio frequencies (RF) test now ARP at progress.For high frequency, aerial (OTA) test can be verifying RF feature only
One method, these RF features (will be included in rule for example including the unwanted emission that radiation sends power (TS 37.145-2) and radiation
In model).
OTA (it is the abbreviation of Over The Air) is a kind of for sending the technology of wireless signal in the sky, different
It is transmitted in cable or electric wire.OTA is an interface, will be used to specifying and verifying highly integrated product, in highly integrated production
It without available ARP and may need to define correlated performance by OTA in product, rather than be used for conventional wireless base station, in tradition
It is specified in the conduction interfaces of similar ARP in wireless base station and verifies performance.
In third generation cooperative programme (3GPP) R-13 version of TS 37.145, the OTA requirement of limited quantity is had been introduced into
(radiation sends power and OTA sensitivity).A kind of idea is to formulate a kind of specification in 3 gpp, has and defines in radiation field
All RF features.This means that needing to test RF parameter under ambient environment, and give a definition in extreme environmental conditions
Certain requirements.(such as radiation sends power, the unwanted emission of radiation, OTA sensitivity to the current special parameter measured using cable
And frequency stability) must be measured by OTA.When carrying out OTA test, absolute radiation power will correspond to equivalent omnidirectional
Radiant power (EIRP), equivalent omnidirectional sensibility (EIS) will be corresponded to by absolutely receiving power.It is real to could be used without related test object
The "black box" method of existing any knowledge, the two parameters will be verified in certain far field antenna test scope, and normal
It carries out having verified that measuring uncertainty is assessed in conditions environmental.
Additionally, there are laws and regulations requirements and/or particular customer requirement, their requirements to pass through OTA under extreme operating condition
Verifying radiation sends power, carrier frequency stability etc..For example, normal operating condition has room temperature and does not vibrate, and pole
End operating condition may have high temperature or low temperature and substantially vibrate.Item suitable for normal operating condition and extreme operating condition
Part is defined and be will be described later by 3GPP.
Based on R&D quality assurance and customer requirement, the range of extreme condition can extend to further include RF feature vibration
Test.For receiver sensitivity, the laws and regulations requirement for not being used to measure in extreme condition, but it is anticipated that client will request
This information.
It is EIRP and EIS in far-field region by the challenge that OTA measures absolute EIRP and absolute EIS under extreme conditions
Middle definition.Distance to far-field region is determined by the physical size and operating frequency of test object antenna aperature.Usual far field away from
From becoming very large, to need large-scale antenna testing tool.In addition, relevant to all types of antenna measurement ranges be,
They are made of high-accuracy mechanical equipment (such as locator, reflector, reference antenna, test scope antenna), these equipment are not
It is designed to operate in big temperature range.If then traversing test model in addition, the equipment operates in extreme temperature conditions
It will be huge for enclosing the energy of needs.According to environmental requirement, the equipment can not be vibrated as needed.
In order to establish the specification for defining all RF in radiation field and requiring, OTA testing tool supplier will be applied and be used for
Dispose impossible task that extreme condition requires.

Point setting can be the band configurations of communication node 103, output power etc. during the measurement of parameter.
Dduring test, communication node 103 can be located in reference position (not shown) or test position 105.
Test position 105 can be adapted with different conditions, i.e. first condition and second condition.First condition is in example
As being different from second condition in terms of temperature and vibration.First condition can be referred to as normal operating condition, and second condition can be by
Referred to as extreme operating condition.When referring to first condition and second condition, term proper testing environment and extreme can also be used
Test environment, normal condition and extreme condition.
The condition that normal operating condition can be described as having room temperature and not vibrate substantially.In normal operating condition
Under, communication node 103 correctly operates and has low component faults risk.Extreme operating condition can be described as having
High temperature or low temperature (higher than room temperature and lower than room temperature) and/or the condition with vibration.Extreme operating condition can for example with
Communication node 103 can be in the highest extreme temperature, minimum extreme temperature, maximum vibration etc. wherein operated.If communication node
103 are subjected to even higher or lower temperature or vibration, then there is the risk that communication node 103 cannot be operated correctly and deposit
In component faults risk.
Under normal operation, test can be executed in certain minimum and maximums limit.These limitations can be by communication section
Manufacturer's definition of point 103.
For example, the Appendix B 2 of the version 13 of 37.141 V13.2.0 of 3GPP TS (in March, 2016) is by proper testing environment
Conditional definition be in table 1 below as defined in minimum and maximum limitation in execute test:
Table 1
In extremely test environment, communication node 103 is subjected at least one extreme parameters, such as extreme temperature (by manufacturing
Decide through consultation justice communication node 103 minimum or maximum temperature), vibration (when communication node 103 is subjected to the vibration defined by manufacturer
When sequence, test can be executed) and power supply (upper voltage limit and lower limit, defined by manufacturer).
In some embodiments it is possible to there are two test positions 105, wherein each test position has specified conditions.
For example, the first test position can have first condition, the second test position can have second condition.In order in different condition
Lower test communication node 105 needs communication node 105 being moved to another position from a position.Note that in order to simply rise
See, a test position 105 is only shown in Fig. 1.
Test position 105 can be enclosure space, usually indoor location.Test position 105 for example can be case or chamber
Room, such as RF anechoic room.Anechoic room is designed to fully absorb the chamber or case of sound or reflection of electromagnetic wave.Anechoic room also with
External noise source isolation.The measurement obtained in test position 105 can be referred to as test parameter or opposite test value.
Reference position can be far field test range or CATR, and have and one of condition in test position 105 (example
Such as first condition) substantially similar condition.The measurement obtained in reference position can be referred to as reference parameter or absolute reference
Value.
Absolute value or number are real number or perfect number.Relative value is dependent on another value either compared with another value
's.For example, relative value is dependent on absolute value either compared with absolute value.
Reference mode 108 can also use in testing with will pass through OTA to communication node 103 send radio wave, with
And the radio wave sent from communication node 103 is received by OTA.Reference mode 108 can be moved in communication node 103
Electric field is scanned on entire antenna aperature.Test equipment 101 can be connected to reference mode 108 via conducting wire.Reference mode 108 can
To be located in reference position or test position 105, or it is located in the two.Reference mode 108 is also referred to as exploring antenna
(when being located in test position 105) and test scope antenna (when being located in reference position).
The radio frequency features of communication node 103 (such as the base station AAS) can be divided into following classification based on quality factor:
1. being based on amplitude (or power) grade another characteristic, such as output power is (equivalent isotropically radiated power (EIRP), useless
Transmitting and sensitivity (equivalent omnidirectional sensibility (EIS)).
2. the feature based on frequency or timing, such as absolute carrier frequency and timing alignment error (TAE).
EIRP is the RF characteristic parameter of communication node 103, can be described as specified or measurement in a single direction
Radiation or send power.The another way of description EIRP is that perfect omnidirectional antenna will need to radiate to obtain the function of measured value
Rate amount.EIS is another this RF characteristic parameter, provides the measurement sensitivity on single direction for communication node 103.
TAE is the RF feature of communication node 103, can be defined as any two signal of the antenna at transmission antenna port
Between maximum timing difference.Absolute carrier frequency should be in specific frequency boundary.If so, it may be considered that having frequency steady
It is qualitative.
In an example (being then explained in greater detail with reference to Fig. 2), two kinds of feelings can be divided by the test that will sum
Condition completes the principle that can verify the RF feature of communication node 103 at ambient conditions:
1. radiating the absolute measurement of RF feature under normal temperature conditions.
2. radiating the relative measurement of RF feature in extreme temperature conditions.
Embodiment herein allows using antenna measurement range (such as the direct far field, deflation operated at room temperature
Antenna measurement range (CATR) or the method based on near-field scan instrument).Absolute measured value under normal condition may be used as in pole
The reference of the relative measurement carried out under the conditions of the temperature of end.Extreme temperature conditions measurement needs the OTA test method of new type, wherein
Communication node 103 is placed in fairly small shielding anechoic room, can easily control temperature in shielding anechoic room.This
Outside, extreme vibration condition can be managed in such test position 105.
In test position 105, for including the relevant position on the antenna aperature in communication node 103, measurement is leaned on
Field strength in the near field of nearly communication node 103 to be tested.Such near field measurement will not provide any absolute measured value,
On the contrary, it can be used for measuring the relative deviation with absolute measured value at room temperature.
Measurement process can be briefly described are as follows:
A. using the absolute reference value under measuring tool A (reference position) measurement normal condition (room temperature).
B. using the near-field coupling value under measuring tool B (test position) measurement normal condition (room temperature).The test point will
The measurement EIRP/EIS rank measured in (a) and the power phase measured near field using measuring tool B (test position 105)
Association.
C. using the near-field coupling value under measuring tool B (test position 105) measurement extreme condition (maximum temperature).
D. using the near-field coupling value under measuring tool B (test position 105) measurement extreme condition (minimum temperature).
E. using the near-field coupling value under measuring tool B (test position 105) measurement extreme condition (room temperature and vibration).
F. the near-field coupling during the vibration under measuring tool B (test position 105) measurement normal condition (room temperature) is used
Value.
The method of this OTA test of processing under extreme conditions needs to work as in tool A and B (i.e. in reference position and survey
Try position in) test RF feature when, the configuration of communication node 103 to be tested is identical.
Firstly, requiring (such as radiation sends power and OTA sensitivity) test communication node 103 according to OTA.The test exists
It is carried out in testing tool A (reference position).
Hereafter, communication node 103 is moved directly into testing tool B (test position 105), can be described as shielding
Silencer box.As described above, reference antenna 108 is located inside case 105, reference antenna 108 can send or receive function by OTA
Rate.Reference antenna 108 can be moved to scan the electric field on the entire antenna aperature of communication node 103.It can be dduring test
Control the environment in terms of temperature and vibration.
In shielding anechoic room 105, temperature can be controlled by following operation: be handed over using external temperature room and circulating fan
It ventilates, or the test position 105 with communication node 103 is placed in large-scale temperature chamber.Based on being set to fc-specific test FC
Standby access, the method that equalized temperature is realized in selection.
EIRP is tested, communication node 103 is then activated with transmitter mode during normal condition.In normal condition
Period detection is by the received power of measurement probe 108 in tool B (i.e. test position 105) and stores the power.It can be with needle
Two cross polarizations are measured.Hereafter, measurement is executed under extreme condition (such as temperature and vibration), and detects reference
Reception power in antenna 108.The difference between the measured value in normal condition and extreme condition can be calculated, and by will be poor
Difference is converted to the EIRP under extreme condition by the measured value being added in testing tool A (such as CATR, reference position).
Can be described as the test position 105 of tool B by being used only, measure frequency stability under extreme condition and
Time unifying error (TAE).First under normal operation, and hereafter extreme condition is applied.In other words, it is not necessary to measure reference bit
Frequency stability and TAE in setting and absolute measured value need not be obtained.This point is described in further detail below with reference to Fig. 3.
Because carrying out environmental condition test in this way needs two different OTA testing tools；One for just
Normal condition and one are used for extreme condition, and test object (also referred to as communication node 103) can have storage and normal condition
The function of associated measurement data.Then, when communication node 103 is subjected to extremely testing, the data stored are used as reference.It should
Data may include at least one of absolute measured value and associated configuration parameter.By placing storage in communication node 103
Device, when calculating the RF feature of extreme condition, it minimizes the risk for using wrong reference.When in testing tool A (reference bit
Set) in when completing RF feature, store relevant to normal condition reference data.
Referring now to Fig. 2 and Fig. 3 description for realizing two kinds of exemplary methods of the test of communication node.Fig. 2 is to show
The parameter that wherein use in testing is an exemplary flow chart of the method for EIRP and EIS.Fig. 3 is that show wherein will be
Parameter used in test is another exemplary flow chart of frequency stability and the method for TAE.In other words, between Fig. 2 and 3
Difference be the RF parameter measured dduring test.
Since Fig. 2.Fig. 2 shows the processes for carrying out OTA EIRP and EIS verifying under extreme conditions.In Fig. 2,
First condition is illustrated with normal condition, and second condition is illustrated with extreme condition.Exemplary method shown in Fig. 2 includes at least some of
Following steps, these steps can be executed with any suitable sequence different from sequence described below:
Step 201
In step 201, communication node 101 to be tested is located at far field test range or CATR.Far field test range or
CATR has normal condition.Test equipment 101 measurement under normal operation with the communication node in far field test range or CATR
103 associated EIRP and EIS values.EIRP the and EIS value of measurement is for example stored in matrix X.Matrix X can have any dimension
N × n is spent, wherein n is any positive integer.
X=[EIRPx EISx]
Test equipment 101 makes node setting (such as band configurations, output power etc.) that can be stored in communication node 103
To be used for all subsequent measurements in (such as memory of communication node 103).
The measurement executed in step 201 can be considered as obtaining the reference measure of reference parameter, these reference parameters are
It is used for the absolute value compared with the other measured values (i.e. relative value) obtained in step below.Therefore, in step 201
Far field test range or CATR during measurement where communication node 103 can be considered as reference position.
In far field test range or CATR, may exist reference antenna 108.Reference antenna 108 can be referred to as far field
Test scope antenna in test scope or CATR.
Test scope on the scene or interior the reference parameter EIRP and EIS measured of CATR are the OTA obtained using reference antenna 108
Measurement.
Step 202
Test equipment 101 checks whether measured EIRP and EIS value meets the requirements.In other words, test equipment 101 checks
(whether the value in step 201) is in the limitation for requiring matrix R by matrix X.It is required that matrix R can have any dimension m ×
M, wherein m is any positive integer.The requirement can be defined by the manufacturer of communication node 103.
If value is unsatisfactory for requiring, this method proceeds to step 203 (indicating in Fig. 2 using "No").If value is full
Foot requires, then this method proceeds to step 204 (indicating in Fig. 2 using "Yes").
Require information (such as matrix R) can be stored at least one of following: communication node 103, test equipment
101, external memory, cloud storage etc..
The requirement can be described for example in the version 13 in 3GPP TS 37.105V13.0.0 (in March, 2016).
Step 203
If measured EIRP and EIS is unsatisfactory for the requirement checked in step 202, the step is executed.Because
Measured EIRP and EIS are unsatisfactory for requiring under normal requirement, so test equipment 101 determines communication node 103 not by just
Operation demonstration in normal condition, i.e. communication node 103 cannot operate in normal condition.
Step 204
If measured EIRP and EIS meets the requirement checked in step 202, the step is executed.By communication section
Point 103 is moved to test position, and test position has normal operating condition.Test equipment 101 measurement under normal operation with survey
Try the associated EIRP and EIS value of communication node 103 in position 105.When the transmission of communication node 103 will be connect by reference mode 108
EIRP is measured when the radio wave of receipts, measures EIS when communication node 103 receives the radio wave sent by reference mode 108.
It is arranged using the node being stored in communication node memory, i.e., communication node 103 has phase in step 201 and 204 the two
Same setting.The EIRP measured in step 204 and EIS are stored in matrix Y.Matrix Y can have any dimension p × p,
Wherein p is positive integer.
Y=[EIRPY EISY]
Step 205
If measured EIRP and EIS meets the requirement checked in step 202, the step is executed.The step can
To execute after step 204, or execute between step 203 and 204.Communication node 103 is still located at test position,
Test position has extreme operating condition now.Test equipment 101 measurement under extreme condition (high temperature and low temperature or vibration) with
The associated EIRP and EIS value of communication node 103 in test position.As described above, when the transmission of communication node 103 will be by reference node
EIRP is measured when 108 received radio wave of point, when communication node 103 receives the radio wave sent by reference mode 108
Measure EIS.Dduring test, the node being stored in communication node memory setting is applied to communication node 103.It can incite somebody to action
Measured EIRP and EIS value is stored in matrix Z.Matrix Z can be any dimension d × d, and wherein d is positive integer.
Z=[EIRPZ EISZ]
Step 206
Test equipment 101 can export the difference between the EIRP and EIS measured in step 204 and 205.Difference can be added
To the value measured in step 201.This can be described as the reference measure in step 201 and the test in step 204 and 205
The comparison of measurement.Therefore, for the EIRP and EIS that are measured in step 204 and 205, by the difference between the value in matrix Y and Z
The value being added in matrix X.Can will be stored in matrix S, matrix S can be any dimension q × q, and wherein q is positive integer:
S=X+ (Z-Y)
Matrix S can be referred to as result parameter, and matrix R, which can be referred to as, requires parameter or requirement.
Step 207
Test equipment 101 checks whether the value in matrix S meets the requirements (identical as the requirement in step 202), i.e. matrix S
Whether in the limitation for requiring matrix R.It is required that matrix R can be defined by the manufacturer of communication node 103.
If value is unsatisfactory for requiring, this method proceeds to step 208 (indicating in Fig. 2 using "No").If value is full
Foot requires, then this method proceeds to step 209 (indicating in Fig. 2 using "Yes").
Step 208
If matrix S is unsatisfactory for the requirement checked in step 207, the step is executed.Because matrix S is unsatisfactory for wanting
It asks, so test equipment 101 determines communication node 103 not by the operation demonstration in extreme condition, i.e., communication node 103 cannot
It is operated in extreme condition.
Step 209
If measured EIRP and EIS meets the requirement checked in step 207, the step is executed.Because of matrix S
It meets the requirements, so test equipment 101 determines that communication node 103 passes through the operation demonstration in extreme condition, i.e. communication node 103
